COPY HOLDER Jesse A. Holton, Sr., West Hartford, Conn., as-v signor toUnderwood Corporation, a corporation of Delaware Application December22, 1944, Serial No. 569,319-

Claims. (01. 120-42) This invention relates to copyholders and withregard to certain more specific features thereof to copyholders of thesmall or portable type adapted, in spite of their light weight andnarrow width, to the accommodation of relatively wide sheets due to thefact that the width of the copy sheet associated with the holder is notlimited by the width of the holder. Such copy' holders employ as a basicprinciple a structure such as is shown in the U. S. patentto Caldwell,No. 216,654.

It it an object of the present invention to provide a relatively smalland easily movable copyholder for the accommodation of long sheets orwebs so that the copyholder is adapted not only for use with ordinarycorrespondence or legal size papers but to stenographic copying orpublic address reading from inscriptions made on very long sheets orrolls.

. It is another object of the invention to provide reliably operativeand inexpensive means for advancing such sheets from a container sectionof the copyholder to a receiver section where, after the completion ofthe copy, the sheet may be conveniently removed from the receiversection by widthwise withdrawal.

It is a further object to provide feed means which may be eitheroperated locally at the copyholder, or by remote control from a machineon which the copy is being made, by incremental movements correspondingto the distance between the lines of write on the copy sheet, and toprovide reliably operative and easily settable means for varying thelength of the incremental movement either under control of the locallysituated mechanical operating devices or the remote-controlledelectromagnetic means for operating the feed means.

It is a still further object of the invention to provide a feed meansemploying coacting rollers arranged to engage the leading edge of thecopy sheet for effectively gripping the sheet to ad-" vance it to thereceiving unit.

Another object of the invention is to mini-- mize manufacturing cost byconstructing the container unit and the receiving unit of uniformshape,and striking from each unit a uniform section which serves in the caseof the receiver unit as a mounting for feed rollers and serves in thecase of the container unit as a mounting for a line-finder device.

Other objects will be in part obvious and in part pointed outparticularly as this description proceeds.

"The invention accordingly consists in the vari' ous features ofconstruction, combination of elements, and arrangements ofparts, whichwill be exemplified by the. following description and the accompanyingdrawings, and the scope of the application of which will be indicated inthe appended claims.

Referring now more particularly to the drawings:

. Figure l is a perspective view of the copyholder.

Figure 3 is a perspective view-. of certain dc-1 tails of the mechanismrelating tothe varying of the incremental feed; and, the means for ad-.justing the mechanism to obtain the variation. Referring now moreparticularly to the drawings, there is shown a stamped metal casing. i0;

comprising a base member II and two upstand ing side walls l2. g-Aremovable plate l3 extends between and is attached to the side walls atthe rear of the copyholder.

Mounted upon the base plate H, of the casing is anupstanding bracket I4which may extend partially across the inside of the casing between theside walls. Secured to a vertical portion of the bracket M as by meansof screw I5 is a volute open-ended sheet metal container member [6corresponding in size, shape and general construction to a voluteopen-ended retainer member I! which is secured to a rearwardly extendingportion of bracket by means of screw [8.

The container member l6 has a portion struck from it to form asupportingarm l9 and the receiving member ll has a similar struck-upportiOljiZfl.

The bracket M has an oblique portion 2| from which two spaced journalarms project, one of.

these arms being shown at 22 and the other is spaced an equal distancefromthe center line of each covered with a band of friction material 21such as soft rubber, felt or other suitable material.

Centrally on the shaftv 24 there is fixed a ratchet, wheel 28 which hasoppositely disposed hubs 29 secured to the shaft by set screws 30.

On the undersideoftheprojection 20 struck- ,out from the vreceivermember. ii is a. eaf sprin The copy sheet is indicated in Figure 2 ofthe drawings at 34 by the dot-and-dash line. In the event that it is along roll, it may be introduced laterally by separating the leadingportion of the roll slightly to pass edgewise into the channel 35 whilethe body of the roll is passed into the body 36 of the container member.Ordinary correspondence or legal sheets may be entered into the volutecontainer memberby' passing the bottom portion of the copy sheet down.through the mouth 31. A straight downwardv movement will enter the.sheet through the channel 35. and around to the required extent in thebody 36.. v

The struck-out arm is of the container member has mounted thereon alaterally extending bar '38 upon whichare mounted two. slidableextension members 39 which serve as a line finder and are convenientlyextensible on the bar 38 and frictionally held. thereon to provide anyreasonable length of line finder desired.

It having been described how the copy sheet may be entered as'shown inFigure 2 ready for feeding, the mechanism for operating the feed meansincrementally and for-varying the incremerits offeed will nowbe'described. Suitable webs 40 provided on the bracket I4 journal ashaft 4| to which securedan operating lever. 42 having a finger-pieceoperating-end 4'3 and a rearward extension 44. Also secured to theshaft. 4lis an arm 45 connected at its outer end to a pawl 46 having anose normally held in engagement with a tooth of ratchet wheel 28 by aspring 48 connected to a lug on the bracket [-4. A detent 50 mounted onthe oblique portion 2lof bracket I4 also engages teeth of ratchetwheel28 for the purposes of correctly positioning the ratchet wheel at theend of an increment or movement and preventing overthrow. Arm 45' andpawl 46 are normally held rearward by a spring 51 secured to thefoot-of: bracket l4 and an adjusting screw 52 determines the normal orrearward position of the arm and pawlby engagement with a lug-53 on arm45.- The adjusting screw 52 is mounted in -abracket 54 adjustablelaterally on the bracket I4" by slot-andshoulder-screw'connectionsindicated in Figure 3 at 55. A spring detent member 56arranged in bracket 54= engages with the edge of one side wall- 12 ofthe casing where it is recessed at 51, anda finger-piece 58 is providedprojecting slightly "outsideof the casing for manipulation of thebracket into any of the positions 1, 2 and 3 indicated by these numbers.1 Alug 59 is turned inwardly onthe" bracket 54 and 'is provided withstepped shoulders which 'a're selectively brought into line withthe'movem'ent of-arm 45-by' 'm'anip-- ulation of the finger-piece 58This provides 'for stopping'the pivotal movement of arm 45 atvary in g'points calculated to allow variable movement of'pawl 46 toproducerotative-movementofieed roller 26 so that'it may be moved to feed thecopy sheet in accordance with the typewritten linechine on whichthecopying is being done.

- therefore, highly desirable to have a control for to its fullestextent will advance the pawl 46 to the particular shoulder stop Bilwhich is aligned with the arm 45, and thus full depression of lever 42advances the copy sheet the required distance. Release of thefinger-piece 43 allows spring 5| to return the arm and present the noseof pawl 35 to a new bite position in the ratchet 28.

The portable characteristic of this type of copyholder enables its readymovement to present the copy sheet in the most favorable light -andposition to suit the operator and frequently this position is at somedistance from the operators hands located at the keyboard of the ma- Itis,

the operation of the feed of the copy sheet located on the typewriter orother machine where the copy is being made. To this end there isprovided a solenoid operation for the lever 42 and its associated arm i5and pawl 36.

The solenoid is shown at. .65 in Figure 2 suitably. mounted on the back.plate l3 and having finger-piece as, and mechanicaloperation of the.feed means, or by depression of the key of switch 64 remote from thecopyholder, and electromag--.

netic operation of the feed means, may cause the copy sheet to beadvanced. incrementally until it; is entirely rolled up in the receiverll, from which.

it maybe quickly and conveniently withdrawn by a lateral movement assoon as its trailing edge:

has passed from. the bite or the feed rolls. For: withdrawing the. copysheet during the copying.

process for the purpose of checking or other pur-:

pose, it isfonly necessary tolift the lip 33, reach behind the paper inthe vicinity of roller 26 and: draw it forwardly, the trailing portionof the paper again taking its position in the channel 3.5- and thecontainer member .16.
